This invention relates to improvements in wringers and more particularly to that type of wringer adapted to be movably mounted upon a washing machine or other suitable support. Such wringers are generally provided with a pivotally mounted drip board for directing the washing fluid or water wrung from wet clothes first to one side of the wringer and then to the other side thereof, as occasion arises for passing clothes from differently positioned wash trays through the wringer. The general object of the invention is to provide eflective means for yieldingly holding the drip board in any desired inclined position for directing the drip water to one side or the other of the wringer.

Other objects of the invention will be readily understood from the following description and the drawings forming part thereof.

In these drawings, Figure 1 is a side view of a wringer embodying the invention. Fig. 2 is an enlarged fragmentary sectional view through the base member of the frame show ing the mounting of the drip board. Fig. 3 is a sectional view on line 33 of Fig. 2. Fig. 1 is a fragmentary side view of the central portion of the drip board. Figs. 5 through 7 show a modified form of the invention in which a special mounting or bracket is used to connect a drip board to the ordinary frame of a wringer. Thus, Fig. 5 is a sectional view through the base of the frame, the bracket and the drip board; Fig. 6 a sectional view of Fig. 5 taken on line 6-6 thereof; and Fig. 7 a perspective view of the bracket attached to and supporting the drip board in the modification disclosed in Figs. 5 through 7. Fig. 8 is a perspective view of a modified form of the yielding pintle. Fig. 9 is a sectional view of a modified base member of a wringer.

Referring more particularly to the drawings, 1 denotes a substantially rectangular frame comprising side stiles or uprights 2 and a base or bottom member 3 and a top member. Upper and lower wringer rolls 4; and 5 respectively are suitably mounted in 0 the stiles 2, the drive shaft 6 of lower roll 5 1932. Serial No. 603,054.

projecting at one end beyond one of the stiles, for convenient attachment of a conventional crank handle, not shown. A pair of guard plates 7 partially enclose the ends of the rolls and also serve as means for pivotally connecting the usual clothes rest or feed plates 8 to the frame. The bottom or base member 3 of the frame is substantially trough-shaped and positioned directly below and in vertical alignment with the rollers so as to readily catch the drip water therefrom, which water. thence drains through a centrally disposed elongated slot Sonto the drip board 10. Extending around and depending from the walls'of slot 9 is a flange 11 formed with oppositely disposed slotted ears 12 to which the drip board is pivotally secured, in a manner presently described.

The drip board 10, preferably of sheet metal, comprises a bottom plate or portion 13 ofslightly concave form and is provided with vertically disposed side walls or flanges 14, which are preferably flared outwardly towards their ends beginning from a common point mid-way the length of the flanges. The upper edges of the side flanges on walls 14 are formed intermediate their ends with 7 round protuberanoes 15, which are resiliently held in frictional contact with the curved bottom face of the base member 3 by means of a pair of substantially Z-shaped pintles 16 made of round or flat spring stock with integral or attached pivot and secured at their outer ends to base member 3 by means of headed bolts 17, these outer ends being formed with eye portions 18 for this purpose. The head portionsl'Z of bolts 17 are preferably pressed into and frictionally engaged with base member 3 to facilitate assembly and disassembly of. the drip board and wringer. The inner ends 19 of the pintles are bent downwardly and thence inwardly in a horizontal plane substantially parallel to the plane of eye portions 18,: and these bent inner end portions extend snugly through openings 20 in the side'flanges and also through elongated vertically disposed slots 21, formed in the ears 12 of the base member 3. The tension of pintles 16 tends to elsvate the inner ends of thelatter and also the drain board, thus causing the round protuberances 15 to engage the corresponding protuberance 22 formed on the base member 3 in the path of movement of protuberance 15.

IVhen the user desires to direct the drip water to one side or the other of the wringer frame, it is merely necessary for him to manually depress one end of the board with sufficient force to overcome the tension of pintles 16, whereupon the board will rock on its pivots until protuberance 15 passes protuberance 22, with an obvious comparative 1y smooth snap action. The board will thus be automatically locked in desired adjusted position.

A slightly modified form of pintle 16' is illustrated in Figure 8, wherein an eye portion 18 is formed intermediate the inner and outer ends ofthe pintle and such outer end 24 is extended to form an additional point of engagement with the base member. An increased resilient or yielding frictional contact between the'parts'is thus obtained.

In Figures 5, 6 and 7, wherein a modified form of the invention is shown, the drain opening 11 is circular, and the flange 12 surrounding this opening is too small to permit of direct attachment of the drip board thereto. Consequently, it is desirable to employ a bracket member 25, having slotted ears 26 depending therefrom. Bracket member 25 is secured to base member 3by the same bolts which attach pintles 16 to said member. The inner ends of the pintles 16 project through the registering openings 20 and slots 21 respectively formed in the side walls of the drip board and in the ears 26 as in the case of the preferred embodiment of the invention.

In some instances the curvature of the base member of a wringer it too flat, to assure proper snap action of the pintles, and protuberances, such as shown in Fig. 3, cannot be used without lowering the drip board,

suspended from the base member. Under these conditions I prefer the arrangements of indentures in the base member as shown in Fig. 9, in which base member 3 embodies two symmetrically arranged indentures 28, separated from each other at 29. This construction is important, where it is necessary to, effect greater springing action of the pintles without lowering the drip board. In structures of the type disclosed in Figs. 5, 6 and 7 these indentures are formed in the bracket.

hat I claim, is:

1. In a wringer, the combination of a frame comprising side stiles and a base, rolls in said frame, said base having a rounded bottom wall with a drain opening therein, a drip board having side flanges, upwardly extending rounded extensions on said side flanges, and means pivotally securing said board to said base beneath said drain opening and yieldingly pressing said rounded extensions on said flanges toward and against the rounded bottom wall of said base to cause vertical movement and locking of the drain board in different positions, when said drain board is tilted with respect to said frame to different post-ions of adjustment.

2. In a wringer, the combination of a frame comprising side stiles and a base, rolls in said frame, said base having a rounded bottom with a drain opening therein, a drip board having side flanges, upwardly extending rounded protuberances on said side flanges, yielding pintles secured to said base pivotally supporting the drip board beneath said drain opening, said pintles pressing the rounded protuberances on said side flanges resiliently against the rounded bottom of said base, to cause vertical upward movement and locking of said drain board when tilted with respect, to said frame to different positions of adjustment.

3. In a wringer, the combination of a frame comprising side stiles and a base, rolls in said frame, said base having a rounded bottom with a drain opening therein, a depending flange circumscribing said opening, said flange having ears formed withv oppositely. disposed vertical slots, a drip board having side flanges formed with openings registering with said slots, rounded protuberances onsaid side fla nges, yielding pintles secured to said base at one end and projecting through the openings in said side flanges and intosaid vertical slots pressing the rounded portions on said side flanges into resilient engagement with said rounded bottom and causing vertical locking movement of said drain board, when tilted to different posit-ions of adjustment.

4. In a wringer, the combination of a frame comprising side stiles and a base, said base having a rounded bottom with a drain opening therein, slotted ears depending from said base, a drip board having apertured side flanges, yielding pintles fixed to said base adjacent their outer ends, the inner ends ofsai'd pintles passing through said apertures and said slots and resiliently pressing said dri board against said rounded bottom of said base, to cause vertical movement of said drain board with respect to said base when said board is tilted to different positions of adjustment.

5. In a wringer according to claim 4 whereby said base includes a separate member provided with said slotted ears and whereby the means to secure said pintles to said base simultaneously secure said separate member to said frame.
